thursday night and final fettling on the mz racer ready for the weekend meeting at snetterton, made some crash bungs out of a pair of old skateboard wheels to protect the shock absorbers and hopefully the seat unit, on starting the bike i noticed that we had a leak from the exhaust manifold so we dropped the pipe 
off and cleaned up the jointing surface and fitted a new exhaust gasket, i had some exhaust wrap left over from the chopper project and decided to use it on the downpipe, i've been on a few two-stroke forums and the general opinion is that the warmer you can keep the exhaust downpipe the better as it encourages a cooler, [more dense] input of fuel/air mix and better cylinder scavenging, don't know if it will work but worth a try and if all else fails it will stop oil spewing all over the place from the leaking exhaust port, had a quick blast up and down the road, totally illegal i know but fuck it, the bike feels crisp and i pull back onto the drive as i'm blipping the throttle dangerous notices the throttle cable un-screwing itself from the carb body, we root around in the spares box and can't find a locknut so i tap a course thread 6mm out to 6mm fine thread and hand file it down to thin it out so we can lock it off, down to the lion garage for some 97 octane fuel, twenty-five quid's worth, i've pre-mixed some silkolene pro-2 race oil into three, five litre cans and i have another ten litre's of 'raw' '97' ready to mix at snetterton, stay tuned for more rock and roll........
